项目摘要
We have established a new method to identify sea ice floes by X-band Doppler radar under various weather conditions. Using Doppler radar data and sea-ice velocity extracted from the cross-correlation method, we have developed a new matching method to derive high temporal and spatial horizontal distribution of velocity fields of sea-ice. Assimilating these values into Japan Meteorological Agency Grid Point Value (JMA-GPV) data, we have applied our sea ice model for short-term prediction of sea-ice and have compared the results with the Doppler radar data.
建立了一种在不同天气条件下利用X波段多普勒雷达识别海冰的新方法。利用多普勒雷达资料和互相关方法提取的海冰速度,发展了一种新的匹配方法,得到海冰速度场的高时空水平分布。同化这些值到日本气象厅格点值(JMA-GPV)的数据,我们已经应用我们的海冰模式的海冰短期预测,并与多普勒雷达资料的结果进行了比较。
